OmniAuth MSU NetID

Build Status Dependency Status


This is the official OmniAuth strategy gem for authenticating to Michigan State University MSU NetID using OAuth2. To use this gem you'll need the following:

  • Contact MSU Information Technology Service Desk at 517-432-6200 to request to register your application, or complete the [OAuth 2.0 request form] (
  • Provide MSU Information Technology Identity Management with a callback URL, which is where to send successful MSU NetID authentication requests back to your application. Note: this must be a HTTPS address.
  • Receive a client_id token and client_secret token specific for your application.


To install this gem you need to add it to your Gemfile as follows: gem 'omniauth-msunet'

Basic Usage

If this is your applications first OmniAuth strategy then you will need to create the file config/initializers/omniauth.rb, otherwise update your existing one.

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :msunet, "replace_with_client_id", "replace_with_client_secret"

Next you need to setup some routes to handle the callback and if it's a success or failure. You could use something like the following in your config/routes.rb file

match 'auth/:provider/callback', to: 'sessions#create'
match 'auth/failure', to: redirect('/')
match 'signout', to: 'sessions#destroy', as: 'signout'

Finally restart your server for all of the changes to take effect. You can now browse to your apps URL to login.

Once the login is completed you should receive the following hash that you can access:

  "name":"John Sparty",
  "description":"MSU NetID OAuth2 Auth-n"
